Hi OS,
mcdu's explanation for the speedy replies says it all.
@ lion-g. The safest way to look after an aeroplane is to leave it in the hangar permanently. Commercial operation involves some acceptance of "risk". I believe the 15 feet clearance from a "wet" runway was acceptable to the legislators because there are far fewer "wet" take offs than "dry" - hence the risk factor is lowered and acceptable.
As mcdu pointed out, choosing a "wet" V1 when it is only damp distorts the safety margins and risk factors adversely.
